GAs-RETon-r.'

steam has been intrmluced into a retort.

through an iron pipe lying on the bottom of the retort. As, however, such an iron pipe burns al'ter it has been in use .for a short time, it was attempted to construct a steam-duct in the wall ot the retort, but without success,

because the inlets trom the duct into the retort were perpetually being stopped up by the coal-dust and products ol distillation. If steam is not constantly issuing,r from these inlets-that is to say, it the admission is only periodical-during tlnintervals of no admission of steam the particles of coal or the like lying in front ol3 or around the inletsv are soon converted into graphite and completely .eut ell' the steam-duct l'rom the interior Vof invention.

the retort.

The present invention eliminates all these objections and also involves the particular advantage that the retort and the steam or gas duct or ducts are indepelnlent of each other in respect of their life.

These objects are achieved by arranging the duct l'or introducing gas or steam into the retort as a piece separate. from the wall oi the retort and not lyinpr within the wall. Thus v Speccation of Letters Patent.

the duct is independent oli the retort and is made olI a refractory material like lire-clay. ln thi` accompanying drawings on:` forni of the invention is illustrated.

Figure l is a vertical cross-section tort having;V tivo ducts made according to the tical section .of the retort .Fig 3 is ,a perspective view of one of the. sections made of refractory material whereof the ducts for the steam or gas that is to be introduced into the retort are constructed.

The retort c has a cross-section such that the bottoni angles b and c are shaped to receive interchangeable duct-sections d which When laid end'to end constitute the gas -or steam duet. These sections have outletopenings e el' suitable form and size, which ai"- ford communication between the passage through the section and the interior of the retort.

of a rei Fig'. 2 is a part longitudinal ver- E, only one.

tical side c ofthe section d rests. .ing the bottom angles band c of the reort are' Patented Feb. 1B,

charging of the retort particles of coal or coke may not enter the o enings e and stop them up, the latter are inc ined, preferably at a sharp angle, toward the bottom of the retort.' Moreover, in the form here illustrated the openingse are beneath a rojeeting art h, whereby when the retort is eing fille vthe openings are not choked.

The cross-section of the steam or gas duct section d is such that it fits the inner contour ofthe angles b and c and the bottom g of the ,'retort. 0n the bottom g is a lon itudinal rib i, against which the lower edgeo the ver- Overhangloneitudinal ribs on the sides of the retort with which a correspondingly-shaped lo tudinal shoulder n on the upper part ofxie section d engages when the section is pushed into the retort from the liront thereof. In this manner tipping forward a lateral shirt of the section is prevented.

Inasmuch as the steam or gas duct sections herein dcscribed are made removable, the repair otone part need not disturb the other parts. This advantage is enhanced by the fact that the ducts are subdivided, so that when a section is damaged only that particular section need be changed for a new one.

Obviously-this invention is not limited to the particular shape and cross-section of the retort and duct-sections shown on the drawings. Moreover, instead of .the two ducts shown in the retort there may be several or 'lhis invention is a plieable with equal advantage to horizonta and inchned retorts.

Having.: now particularly described and ascertained the nature of my said'inventzion` and the best means I know of carrying the same into eli'ect, I claim.-

1. In combination, a retort, interchangeable tubular sections of refractory material together forming an independent ductfreinovably combined with the retort, and assages leadingv from the interior of said uct xinto the interior of the retort.

2.-,In combination, a retort, an independ-- ent dd'ct of refractory material, removably combined therewith., so as to form a continuation thereof in cross-section, downwardlyinclined passages leading from the interior of the said duct into the interior of the retort, and a longitudinal projection on thesaid duct In order that during the charging or d isover the said passages.

3. In cgrrflbination, a retort und interchangeable sections/ot retrtxetory nutteliztl together for1nin;r mi independent duet, tl-te Said sections ybeing removably '.on1l.\int\l with the retort so as totottn l:t (-ontiuutttion thereo in Grone-section. dounn'nrdtv-inclined passages leadingr from ttte interior of each section into the interior of tlie retorty t and a longitudinal projet-.tion on enr-lt sec-tion over the said passages. 4. In combination, ft retort, a longitudinal t rib-ontlle bottom tltereot, longitudinal ribs j on the sides thereof overlanglingr tlte bottom singlesl thereof, duct-sections of retrait-,tory l' material, a longitudinal shoulder on each sce l tion adapted to engage the said longitudinal ril) on tlte side. of the retort, ny vertical lQide to enel) set-.tion adopted to engnjge said. longitudinal ril) on tlteA bottoni ol' tlte retort. :1nd tlo\\'n\\'zn'dlytliret'ted pnssnges zo lending; troni tlte interior ol enelt ser-tion into tlte interior ol' tite retort.
